note 100344 added to function.similar-text

Following functions is much more efficient for comparing short strings (say up to length 100). It checks strings for containing same character PAIRS, rather than single characters. This better captures differences in sensible text. function getSimilarity($str1,$str2) { $arr1 = str_split($str1); $arr2 = str_split($str2); $i = 1; $count = 0; while(isset($arr1[$i])) { if(strstr($str2,$arr1[$i-1].$arr1[$i])) $count++; $i++; } $i = 1; while(isset($arr2[$i])) { if(strstr($str1,$arr2[$i-1].$arr2[$i])) $count++; $i++; } return $count / (strlen($str1) + strlen($str2) -2); } ---- Server IP: 69.147.83.197 Probable Submitter: 83.208.36.244 ---- Manual Page -- http://www.php.net/manual/en/function.similar-text.php Edit -- https://master.php.net/note/edit/100344 Del: integrated -- https://master.php.net/note/delete/100344/integrated Del: useless -- https://master.php.net/note/delete/100344/useless Del: bad code -- https://master.php.net/note/delete/100344/bad+code Del: spam -- https://master.php.net/note/delete/100344/spam Del: non-english -- https://master.php.net/note/delete/100344/non-english Del: in docs -- https://master.php.net/note/delete/100344/in+docs Del: other reasons-- https://master.php.net/note/delete/100344 Reject -- https://master.php.net/note/reject/100344 Search -- https://master.php.net/manage/user-notes.php
